The vlve is designed to let the wter pss the filter from inside to outside to void clogging. The sme shut-off vlve is used on System 2000, Freedom Bth. 1. Close the vlves. The hndles (red for hot wter nd blue for cold) should be in cross position. WARNING Mke sure tht the vlve is closed before removing the lid, especilly importnt on the hot wter supply. Filter Hex hed lid 2. Remove the hex hed lid with wrench. 3. Pull out the filter nd clen it crefully. 4. Open the vlve for while. NOTE When flushing the vlve use hose to led out the wter in vessel outside the bth to ctch up the wste wter. 5. Shut the vlve 6. Fit the hex hed lid 10

RPE SOLENOID VALVES These vlves re replced complete if not functioning. They hve n expected lifetime of openings nd closings. See pge 50. OLD SOLENOID VALVE (Fill vlve) The solenoid vlves hs membrne s well s n nchor sel. Membrne The membrne (4) is locted underneth the brss lid (2) nd is ccessed fter removing the four Allen hed screws. When removing the lid; note the position of the membrne s there is smll bleed hole nd brss pipe in the membrne (A) tht hs to be ssembled correctly to function. The membrne is lso equipped with pressure trnsition hole (B), llowing the pressure to build up on top of the membrne thus keeping the vlve closed. As the trnsition hole hs to be cler of ll obstcles nd dirt to function stisfctory, the hole hs n inserted brss pipe (very smll) to prevent lime build ups. This pipe must not be removed or the result will be tht the vlve does not close. Anchor sel The nchor sel on the nchor (6) is locted under the nchor housing (7) nd is reched by loosening nd removing the solenoid (1) nd the nchor housing. Be creful not to loose the nchor spring on the nchor. The service kit for this vlve includes position 4, 5, 6 nd 7. Membrne condition Focus should be on the membrne rubber sttus: it should not stin your fingers when touching it or show signs of deteriortion.

If the flow nd pressure of the incoming wter is OK then mesure the flow from the shower, (defult 4,9-5,7 l/min) by filling vessel with known volume 3. Clculte the flow by dividing the volume of the vessel with the time to fill the complete vessel e.g. 20 l /4 min=5 l/min 4. Perform the test twice 5. If the verge flow is 4-5 l/min or more there is no need to replce the flow restrictors 6. If the verge flow is less thn 4 l/min both the fill vlve () nd the pump vlve (b) must be replced, follow the replcement procedure below. Replcement procedure )Fill vlve b)pump vlve 1.

13 MRM Mlibu/Sovereign Service Procedures SP 8. Check/Adjust Mixer Including Sel Kit/Complete Thermosttic Unit For mixers instlled in ny UK Ntionl Helth Service Instlltion. Plese refer to document 10.AR.03. If the mixer does not provide sufficient mount of wter or if the temperture regultion/stbility is poor: Check incoming flow, pressure nd temperture Check tht hot wter (stble 40 C) is shut off if incoming cold wter check vlve is closed Clen filters incoming wter ccording to SP 5 Check shower hndle flow ccording to SP 10 Check fill flow using the tub filling times in Instructions for Use. If incoming flow, pressure nd temperture is OK nd the procedures bove re mde but the temperture regultion/stbility or flow still is poor, replce the regultion crtridges s follows: All crtridges with springs () shll be replced if mintennce is required. These re included in repir kit together with o- rings nd internl check vlves. The three pushers (b) nd the shft trnsmission must be well lubricted or it will be difficult to djust the temperture. (Lubriction see pge 50) As the mixer is difficult to serve in plce it s recommended to strt with disssembling the mixer. b Disssembling the mixer from the tub 1. Reching the mixer from the short side will simplify the procedure but is not necessry 2. Shut off the wter supply 3. Rise the tub to top position 4. Remove the front pnel nd inner cover 13

Turn the plstic prt (d) counterclockwise until the correct temperture is mesured. (see pge 26 for set vlues). Try to get s close s possible to this temperture s over temperture will ctivte the sclding protection nd shut off the hot wter. Remember tht the fill wter setting results in shower temperture round 3 C below the fill setting. 4. Leve the wter on for 30 seconds so the wter temperture is stble (For Mlibu without shower go to 6) 5. Now ctivte the shower, mke sure the shower temperture hs the correct mximum vlue. If exceeded the regultion crtridges need to be replced, see pge Push the knob in position. The stop peg on the knob (c) shll be plced just bove the stop peg of the stop ring (e). In this position it shll be impossible to turn the knob counterclockwise. 7.
